It seems Microsoft's Xbox One is apparently failing to match Sony's PlayStation 4 sales figures. As noted Microsoft writer, Mary J Foley says a source within Microsoft has told her that Microsoft has sold only 18 million copies of the console.

Sony Computer Entertainment has announced that during the holiday season (23/11 - 2/1) the company sold more than 5.7 million PlayStation 4s. This brings the total number of PS4s to more than 35.9 million as of January 3rd.
